The Automated Water Heater Controller is an Internet of Things (IoT) project that combines Notification service and Device controller, built with Blynk. The project follows a clean, modular pipeline where sensor data acquisition, connectivity, and presentation stay separated, making it easy to test, extend, and present. It showcases practical IoT techniques while producing a working, demo-ready system.
Manual monitoring and control for this task is slow, inconvenient, and cannot be done from anywhere. Without an IoT approach built on Device controller and Blynk, users cannot connect real-world devices to the internet and manage them efficiently in real time.
This project applies IoT techniques through Notification service, orchestrated with Blynk and Device controller. The system is designed for connectivity and reliability, with sensing, networking, and clear evaluation. It produces consistent, reusable results and can be adapted to related connected applications with minimal changes.

The project is layered: the sensing layer acquires data through Notification service; the connectivity layer publishes and processes it with Blynk and Device controller; and the output layer monitors and controls via Automation rules. Shared connectivity, alerting, and dashboard modules support all layers, keeping the system robust and easy to extend.
